2015 May Day activities in unigeogrid markdowns Chen Phone: 136394508091, geogrid geogrid is a major geosynthetics, compared with other geosynthetics, it has the unique performance and efficiency . Geogrid used as reinforcement or composite materials, such as reinforced soil reinforcement structure. Into plastic geogrid geogrid, steel plastic geogrid, fiberglass geogrid, and polyester fiber geogrid four categories. (1) plastic geogrid plastic geogrid is the result of a polymer mesh material with a square or rectangular stretch forming, different stretch and two-way stretch stretching direction of its manufacture is unidirectional. It was punched out by squeezing polymer sheet (mostly raw materials, polypropylene or high density polyethylene), and then the purposes of orientation stretch under heating conditions. Grid made of stretched only uniaxially stretched along the longitudinal direction of the sheet, while the two-way stretch grille is continued to the grid and then uniaxially stretched in a direction perpendicular to its length stretching is made. As the plastic in the manufacture of polymer geogrid polymer would rearrange the orientation process with the heating extend and strengthen the link between the molecular chains force, to improve its intensity. Elongation is only 10% to 15% of the original sheet. If the addition of carbon black and other anti-aging material geogrid, you can make good acid and alkali, corrosion resistance and durability can have anti-aging. (2) bi Biaxial geogrid is polymer by extrusion, into a plate, then punching process vertical and horizontal stretching from. And assume an ideal diffusion of the material of the chain system in the vertical and horizontal great tensile strength, such a structure in the soil also provide a more effective force, is adapted to carry a large permanent in Ground unigeogrid unigeogrid is extruded polymer pressed into sheets and then washed rules mesh, and vertical stretching. This process, polymer and formed into a linear state directional distribution uniform node strength oblong mesh overall structure. This structure has a very high tensile strength and tensile modulus, especially my company such products more super high international level of early (elongation 2% --- 5%) Tensile strength and tensile modulus. Soil provides the ideal force commitment and the proliferation of chains. The product tensile strength (> 150Mpa), to adapt to a variety of soil, is currently widely used in reinforced reinforcement. (3) Plastic Geogrid Plastic Geogrid to high-strength steel (or other fiber), with a special treatment, and polyethylene (PE), and add other additives, become through out the tensile strength composite bands, and the embossed surface roughness, compared with high-strength geotextile reinforcement. This single band, the vertical and horizontal spacing of the preparation or clamping arrangement, using a special welding technology welding to strengthen bonding and molding of their intersection, was reinforced geogrid.
